Women's Knowledge of Future Cardiovascular Risk Associated with Complications of Pregnancy: A Systematic Review

Background:Several common pregnancy conditions significantly increase a woman's risk of future cardiovascular diseases (CVD). Patient education and interventions aimed at awareness and self-management of cardiovascular risk factors may help modify future cardiovascular risk. The aim of this systematic review was to examine education interventions for cardiovascular risk after pregnancy, clinical measures/scales, and knowledge outcomes in published qualitative and quantitative studies.Methods:Five databases were searched (from inception to June 2023). Studies including interventions and validated and nonvalidated measures of awareness/knowledge of future cardiovascular risk among women after complications of pregnancy were considered. Quality was rated using the Mixed Methods Appraisal Tool. Results were analyzed using the Synthesis Without Meta-analysis reporting guideline. Characteristics of interventions were reported using the Template for Intervention Description and Replication. Fifteen studies were included; 3 were randomized controlled trials.Results:In total, 1623 women had a recent or past diagnosis of hypertensive disorders of pregnancy, gestational diabetes mellitus, and/or premature birth. Of the 7 studies that used online surveys or questionnaires, 2 reported assessing psychometric properties of tools. Four studies used diverse educational interventions (pamphlets, information sheets, in-person group sessions, and an online platform with health coaching). Overall, women had a low level of knowledge about their future CVD risk. Interventions were effective in increasing this knowledge.Conclusions:In conclusion, women have a low level of knowledge of risk of CVD after pregnancy complications. To increase this level of knowledge and self-management, this population has a strong need for psychometrically validated tailored education interventions.
